Review on 🚴 Enhance Performance with Vittoria Air Liner Insert Green Extra by Brandon Show

Wanted to use this to keep my tubeless 20x4 tires from losing bead on a cold morning commute. This could help prevent rim damage. but the foam can be 3 inches wide, not wide enough to fill the tire more than 1/2 of the way. The diameter isn't wide enough either, even if I halve it lengthwise to "fix" the edge of the bead from the inside. Came back because it advertised 4" wide tires but clearly wasn't designed for it and I won't assemble anything and use $80 foam that doesn't work and I can't return if that fails. I'm sure, this works well for narrower drives.I ended up using rubber/silicone grommets on the inside of each rim cut with about 1/4 space between the rubber edge and the rim edge to hold the tire in place.. Push in with tire spoons, pour in some tire sealant , inflate, hear the tire bead seat "pop". That tire bead is sealed! 3 months of commuting on a 90lb bike with no bead loss in low pressure/freezing weather.
